So i want unit to just turn with left click of the mouse and not move it!
cant find a way what to modify, any idea how to do this?
You could always just change the rotation of the actor using events
Contribute to the wiki (Wiki button at top of page) Considered easy altering of the unit textures?
When Player presses Mouse Down
Order unit to Face Point (Point(Mousex,MouseY))
Triggers will be your friend. What Dustin said is what I would try first.
